    My house is maxed out for what is practical for solar panels given the layout. I get on average 55 kWh a day in power generation. It takes 92 kWh to fully charge my Model Y.

    So if my house solar system was dedicated to charging the car, it would take 2 days to fully charge the car. In reality it would take over a week.

    I suppose if someone lived in Arizona and had many more panels than I do, then this would work. Certainly, it’s not practical for everyone.

        This is an important distinction. I usually charge to 85% daily. Going below 55% in a days driving for me happens maybe twice a month. Basing use cases on the idea of charging from 0% is not realistic at all.

      Maybe best to think of it as “soak up solar” i.e. send any excess solar to the car rather than accept mediocre feed in tariffs. Are least that is how I have been using the equivalent feature I have set up in Home Assistant.
